Aliza needs to run at a rate faster than 8.8 feet per second in order to exceed her fastest time in a race. after running for 15 minutes, her coach determines that she is running at an average rate of 5.8 miles per hour. he converts the average rate to feet per second as shown below: he concludes that she is not running fast enough to exceed her fastest time. what errors did the coach make?

she needs to beat 8.8 ft /sec which is 0.001667miles/sec and after 15mins,she ran 0.00161miles/sec.
